My invention relates to rod couplings, and the externally threaded portion 3a adapted to coobjects of my invention are: act with thei internal thread 2a of the sleeve 2, First, to provide a coupling-which is adapted and a frusto-conical head portion 3b having to hold a pair of rods in axial alinement; notches therein adapted to be engaged by a sult- 5 Second, to provide a coupling of this class able tool. 5

which may be made particularly compact yet is The head portions are smaller in diameter than capable of withstanding any of the tension or the sleeve and tapered so that when the coupling compression strains within the strength of the is inserted in a pipe as when used in conjunction rods connected thereby; with sewer cleaning rods, they cannot engage the l Third, to provide a coupling of this class in walls of the pipe. Thus the rods maybe turnedin lo which the parts are few in number and particeither direction without danger of the collars ularly simple of construction, thereby providing working loose. a coupling which is eccnomical'cf manufacture; The bore through each collar 3 is adapted to and center the rod relative tothe sleeve 2, thus when l Fourth, to provide on the whole a novelly contWo rods are positioned in the' sleeve 2 and the l5 structed rod coupling which is durable, efficient collars 3 are secured, the rods are in axial alinein its action, and which will not readily deteriorment as shown in Fig. 2.
